 A VectorCraft addition, not a feature of the reference app, so no area score moves. Object › Plug-ins › Path Precision Tools › Divide into Dashes… cuts the selected paths into separate open paths along the curve (arc length, not straight distance): each `dash` long (0.01 to 1000000 pt, 10 by default) with `gap` between them (0 by default: the pieces touch); the gap pieces are left out unless Remove Gaps is off. With direct-selected segments (or anchors) only those runs are divided, the pattern running on across segments that follow one another, and the rest of such a path stays as pieces of its own. Fit to Corners and Ends gives every run between corners and ends a whole number of dashes, all stretched or squeezed alike so it starts and ends on a dash (a closed path without corners holds whole periods); otherwise the lengths are exact and each run's last piece is what is left. Every piece keeps the path's appearance and is selected; one undo step; at most 100000 pieces (more is refused). The dialog takes lengths in any unit and previews on the canvas. Tests: `dashes::tests` in `vectorcraft-pathops` (exact and fitted lengths, curves measured along them, picked segments on open and closed paths, the piece cap and bad patterns), `divide_into_dashes_*` in `cmd::addons::pathtools::tests` in `vectorcraft-engine` (gaps removed or kept, fitted lengths, the stroke kept, one undo step, selected segments only, bad params and too many pieces refused), `divide_into_dashes_opens_its_dialog_previews_and_runs_on_ok` in `vectorcraft-ui-egui` and `command_sweep`.

+A VectorCraft addition, not a feature of the reference app, so no area score moves. Object › Plug-ins › Path Precision Tools › Expand Dashes into Paths turns the dashed stroke of each selected path and compound path into separate open paths, one per dash, for cutters and plotters that need the centre lines rather than Outline Stroke's filled outlines. The dashes are laid out by the renderer's own dash code, so they match what the canvas draws: the dash pattern, its offset and Align Dashes to Corners and Path Ends, a dash running on through the start of a closed path, a dash all the way round staying closed, and under a round or projecting cap each dot (a dash of no length) as a path on its point. Each dash keeps the path's appearance with the top stroke's dashes and arrowheads off; the path's fills stay on it, below its dashes; a compound path's dashes are plain paths. One undo step; the dashes are selected; at most 100000 (more, or a pattern too fine to draw, is refused). Tests: `expand_dashes_*` in `cmd::addons::pathtools::tests` in `vectorcraft-engine` (the stroke kept with dashes off, the offset, one undo step, the fill kept below, dashes centred on corners when aligned, dots under round and butt caps, compound paths, refusals and the piece cap), `the_plugins_submenu_selects_the_tools_and_opens_the_anchor_inspector` in `vectorcraft-ui-egui` and `command_sweep`.

 ## Document Tools add-on: Save a Timestamped Copy (2026-11-01)
 
 A VectorCraft addition, not a feature of the reference app, so no area score moves. Object › Plug-ins › Document Tools › Save a Timestamped Copy writes a copy of the document named `<name>_YYYY-MM-DD_HH-MM.<ext>` (the date and time in UTC, through chrono; `-2`, `-3`… added when that name is taken) next to the document, or into a folder picked (the folder picker) when it was never saved, in the document's own format or another save format. It writes through File › Save a Copy's save, so the document keeps its path, title and modified state, no undo step is made, and the write stays inside the automation roots in force. It is off on the web, which has no clock. Tests: `cmd::addons::document::tests` in `vectorcraft-engine` (the name and place, numbered names, the document unchanged and its content in the copy, an unsaved document needing a folder, other formats, bad params refused, automation roots), `addons::document::tests` in `vectorcraft-ui-egui` (the submenu, beside the document, the folder picked or cancelled) and `command_sweep`.
